Becky, where did you get the numbers you listed? If you got them from the NGA database it may not have been updated from a previous update to the AHS database.The number of registrations for 2016 changes as registrations continue to be recorded and are updated to the AHS database, it's important to look at the last updated date which currently is 2016-08-09. When I do a search of the AHS database for 2016 I get 1601 daylilies.
The cut off for each years registrations is Nov. 1st. This means for inclusion in the 2016 registration checklist (printed in the spring of 2017) the 2016 registration window is open Nov. 1, 2015 to Oct. 31, 2016. Daylilies registered on and after Nov. 1, 2016 to Oct. 31, 2017 will be listed as 2017 registrations.
Edited to change ATP database to NGA database. Duh moment.
